The southwest part of the state, the Upper Rio Grande and the combined San Miguel, Dolores, Animas and San Juan basins, are suffering through another below normal snow year. While the combined San Juan basins did see a 3 percentage point increase from this past month, that put them at 85 percent of median, the Upper Rio Grande basin lost five percentage points, dropping to just 79 percent of median.

Streamflow forecasts for the Colorado River Basin point toward above to well-above normal volumes for this spring and summer, Phillips said.
